O.k. I've got some questions about what is happening in a tube amplifier when the speakers are run off the 4 ohm taps instead of 8 ohm taps.
On a SS amp, this is not an option, though depending on the amplifier there is sometimes concern about running a pair of 4 ohm speakers in parallel. I've got a couple of pro sound amps used by my youth group that can run into 2 ohm loads all night and not sweat it.
I think I can remember Craig suggesting to discover whether I preferred the sound of my Scalas running off the 4 or 8 ohm taps of my first 299. Never did check that out, seemed too much like work.
From time to time I will set up a Heresy center with my Khorns and run the output through a Dynaco QD2 to derive a center channel and run all three speakers off two monoblock amps. The sound is impressive.
Someone shared with me a week ago that the rigged as such, the QD2 presents a 6 ohm load to the amps. So I thought, might be a good time to change to the 4 ohm taps to see what it sounds like. I switched and am running the Wright 2A3 monoblocks off the 4 ohm taps through the QD2 to the Khorns and Heresy center. Wow.
To my ears, the whole sound, especially the mid bass and bass sounds easier, fuller, richer, effortless. I didn't really know what to expect.
One thing I'm wondering is... what is going on in the amplifier running of 4 ohm instead of 8 ohm taps?
How does a SS amp manage w/o different taps?
What if one runs 8 ohm speakers off 4 ohm taps all the time?
Is the difference in sound completely subjective? Could it be measured with instruments?
My daughter (in engineering school) just gave me her textbook from an intro to electronics she had this semester. So I'm in kindergarten.
Appreciate any help here. Talk real slow please.
